New to totes, Our Mens Single Eco Supersoft Socks have been sustainably produced for you using recycled polyester. To bring these socks to life, two plastic bottles are washed, crushed, decomposed, polymerized and granulated into chips. These chips are melted in a spinning process to create the recycled polyester yarn. Thank you for supporting our efforts to create a more sustainable planet. We hope you share the same pride wearing these socks as we did to make them. Warm your feet, not the planet! Please look after these socks sustainably and wash at an environmentally friendly temperature.
